BOOKBINDER.

Specification of Letters Patent.

Application filed March 10, 1913.

Patented Dec. 30, 1913.

Serial No. 753,286. I

To all whom it may concern:

Be it known that I, CI-IESLEY DOM, a citi- Zen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Bookbinders, ofwhich the following is a specification.

My invention relates to an interchangeable pamphlet or book-holder, fortelephone books, catalogues and the like.

The object of the invention is to produce a simple, cheap and easilyoperated, interchangeable book-holder, which will securely and yetinterchangeably hold the book in a stiff binder without injuring thebook or in terfering with the convenience of usage.

The features of invention will be more fully set forth in thedescription of the accompanying drawings, forming a part of thisspecification, in which Figure 1 is a plan View of the booloholder. Fig.2 is a longitudinal section through Fig. 1. Fig. 3 is a section on line50, 00, Fig. 1. Fig. 4 is a perspective view of the applied book-holder.

- In the preferred embodiment of the invention illustrated in thedrawings, my device comprises a base 1, such as a longitudinal strip ofwood or other suitable material, forming a support for the book bindingedge.

2 represent the covers hinged to the base 1 by means of the flexiblecovering 3. At one end of the binder formed by these elements (2'. c.the lower end of Fig. 1) is a. longitudinal strip of metal 4, secured onthe inner face of the base 1 6. between the binder covers 2 whenclosed). Preferably this strip has the curved and medial flat surfacesillustrated in cross section, Fig. 3, the curved por tions constitutinglongitudinal reinforcement. The lower end of strip 4 is turned up toform the flange 5 forming an end abutmentt'or the book held within thebinder.

6 is a flexible, say wire hook, secured to the base 1, and overhangingflange 5, to be inserted between the open pages of the book or pamphlet10, as shown in Fig. 4. V

7 represents the rivets passing through the base 1 and the flat, medialportion of the strip 4, the holder element for this end of the bookbeing fixed relative to the binder. The holding element for the otherend of the book comprises the metal strip 4 corresponding structurallyto strip 4, but formed with the medial longitudinal slot 8, the outerend of strip 4 being turned up to form the end flange 5, the hook 6being fixed to strip .4, and overhanging flange 5, in correspondence tothe relative structural arrangement of the first described holderelement.

9 is a flat strip of metal, slightly bowed longitudinally to constitutea spring tension member, secured over strip 4, by means of rivets orscrews 11, passing through slot 8, and thus securing these elements tothe base, enabling the longitudinal adjustment of the upper holdingelement, under sufficient tension to frictionally retain a set position.

In operation, the movable holder element is extended the book opened upand placed between the binder covers, as shown in Fig. 4, hook 6engaging between the open sheets, thus gripping one end of the book, thehook 6 is then closed in to grip the other end of the book between theopen pages. The book or pamphlet of flexible cover style, is thusincorporated between st-ifi covers, so that it may be handled as aunitary structure.

The book will be preserved from injury, can be conveniently handled, andthe binder is readily interchangeable.

Various modifications can be made by the skilled mechanic in viewof'this disclosure of the preferred embodiment of my in vention.

Having described my invention, I claim 2- In a book-holder, a base, abook gripping element comprising a strip of metal secured thereto at oneend, and formed with an end flange, for engaging one end of the book,and with a hook overhanging the flange for engaging between pages of thebook, a second corresponding lock gripping element, formed with a mediallongitudinal slot, and a friction member securing the second grippingelement longitudinally adjust-- ably to the other end of the base.

In testimony whereof, I have hereunto set my hand.

CHESLEY DOM.
